I am developing a game in Unity3D. I want an enemy character to follow the player around. The problem is, my surface is uneven and full of mountains. I am using aarongranberg's pathfinding project. Every time that a player climbs a hill or a mountain, the enemy stops because the grid is flat and it considers the mountain to be an obstacle. How do I solve this problem ?

Don't make mountains an obstacle, just give them a higher cost than flat land... –  BlueRaja - Danny Pflughoeft Aug 29 at 17:41

Read the instructions on how to use your pathfinding library? Setting path-costs is a basic prerequisite for using A* on a graph. –  BlueRaja - Danny Pflughoeft Aug 29 at 18:01

Maybe post an answer of how you solved your specific problem afterwards and accept it. –  Larethian Aug 29 at 21:50
